I n u p a o I r Patented F ch. 3, 1931 PATENT RICHARD W. DINZL, BYWOOI),PENNSYLVANIA, ASSIGNOR TO SOIJ'THWARK FOUNDRY & MACHINE COMPANY, OFPHILADELPHIA, PENNSYLVANIA, A CGRPORA- rrron or "PENNS LVANIA 'HOSEPRESS Application filed July 19,

One object of my invention is to provide a hose press of extreme length,which :structure includes a horizontal base or bed, with matching diemembers or elements, pref-en ably in the form of steam platens, each dieelement having a plurality of semi-circular recesses forming moldcavities in which lengths of hose may be cured; the lower d-ie elementor platen being-fixed to the base while the upper die element or platenis vertically movable with respect to the same. By preference, these dieelements or platens are of such dimensions as to :provide a series ofrecesses in parallel arrangement widthwise of the same, so thataplurality oflengths or" hose can be molded and cured at a.single'operation.

A further objectoi my invention is to provide upper and lower diemembers or elements of extreme length in the form of steam platens,which may be solid metal plates of the type set forth in my Patent No.1,549,464, dated August 11-, 1925, heated by the circulation of steamthrough continuous passages formed in said platens by drilling .in themanner set forth in said patent.

A further object of my invention is to provide longitudinal stiffeningmembers for the upper die element or platen in order that it may bemaintained in a truly horizontal condition for proper engagement andperfect registry with the lower die element or .platen.

A further object of my invention is to provide lifting means for theupper die element or platen, and to associate such lifting means withclamping means carried by said upper die element or platen'forengagement with the lower die element or platen; such clamping meansbeing thrown into and out of clamping position automatically,simultaneously with the operation of lowering and raising the upper dieelement or platen.

And a still further object of my invention is to provide means wherebythe upper. die element or platen maybe lifted from :a plurality ofpoints simultaneously bythe opera tion of .a single fluid-operatedpiston contained within a cylinder mounted above the press. I

These and other features "of my invention 1926. Serial no. 123,520.

tion of the structure shown in 1 Fig. 2, being partly in section andFig. 3, being in greater detail. I

Figs. 4 and '5, are cross sectional views on the line III-III, Fig.2;showing the upper platen or die-member in the closed and open positions,respectively.

6, is a diagrammatic plan view, showing the respective die members orplatens partly in top view and partly in section, and

Fig. 7, is an enlarged sectional view illustrating a detail of myinvention.

. My improved hose press comprises upper and lower matching the memberswhich, in the present instance, are in the form of steam platens,longitudinally grooved to provide mold cavities for the hose lengthswhen said die members are'in closed and registering position; suchplatens being provided with continuous internal passages, preferablyarranged'in sectionsior the-circulation of a temperature controllingmedium, usually steam, as set forth in my patent above referred to, andtheselpassages may be arranged in groups or sections. v

The lower die element, indicated at 1, may be supported by I-beams 2,embedded in a concrete base such I-beams being spaced apart andpositioned by means of bolts 4. The lower dieelement or platen islongitudinally grooved in parallel relation, as indicated at 5,to formthe lower halves of a series of mold cavities for hose lengths, orarticles of similar nature. The upper die element or platen, indicatedat 10, is provided with similar recesses 5a, registering with those'ofthe lower die element or platen, and such upper die element or platen isstiti'ened longitudinally by means of I-b'eains 11, which may be securedthereto by suitab'le'bolts' 12.

Pivotally connected at each side of the upper die element or platen,throughout the length of the same are clamping levers 15; the edges ofsuch upper die member or platen being provided with brackets 16, securedthereto by bolts 17,1n which pivot pins 18,1tor said clamping levers aremounted. The lower ends of these lovers are provided with inwardly proectin por 10118 19, which underlie the edges of the lowerdie element orplaten when in the clamping position, and these projecting portionscarry adjustable clamping blocks 20, secured thereto by bolts saidblocks being interposed between the projecting portions and the edges ofthe lower die element or platen, when the press is in the closedposition, as indicated in Fig.4. Between these projecting portions 19,and the blocks 20, removable. liners or shims 22, are placed, for apurpose hereinafter described.

The upper ends of these levers 15, are connected with brackets 25,carried by an E-beam 26, extending longitudinally of the press, by meansof links 27, and such I-beam in turn is supported by cables 28, passingover sheaves 29, carried by a supporting frame 30; the opposite ends ofsaid cables being connected to the end of a piston rod 31, whose piston32, lies within a cylinder 33, also mounted on said supporting structure30. This supporting structure may consist of a pair of I- beams 35,secured together in the form of a truss and suitably supported above thepress, longitudinally of the same.

The several cables 28, are connected to the Lbeam 26, by adjustableshackles 34, so that the respective cables can be properly adjusted toinsure that any motion of the piston to elevate the I-beam 26, carryinthe upper die element or platen will be synchronous; and in like manner,when it is desired to lower the upper die element or platen, a graduale.\'- haust of fluid-pressure from the cylinder 33, will permit theupper die element or platen to maintain its horizontal position whilebeing lowered upon the lower die element or )iston. When the parts ofthe lifting mechanism are in the lowered position, indicated in Figs. 2,3, and st, she links 27 are spread apart by their bracket connectionswith the I-beam'26, so as to push the upper ends otthe levers l5outwardly, and bring the inwardly projecting portions with the clampingblocks 20, under the edges of the lower die element or platen I. Theplatens or die elements of the pressare maintained in the closedposition by the clamping levers 15; the spreading of the links 27 causinthe lower ends to grip the same between the points of contact and thevpivot pins 18.

As the upper die element or platen is lowcred into place,the projectingportions of the levers 15 pass under the lower platen; further downwardmovement spreading the upper ends of the levers 15, and crowding theprojecting portions 19, with the blocks 20, beneath the edges of thelower platen. To insure an even pressure upon the edges of the platensthe blocks 20 may be adjusted to proper position by the insertion ofliners or shims 22, between the same and the projecting portions 19.Upon imparting a lifting movement to the I-beam' 27, when it is desiredto raise the upper die element or platen, these clamping blocksareautomatically released; the connection of said beam with the linkscausing the latter and the levers to assume the position shown-in Fig.5, with the lower engaging portions of such levers displaced outwardly,as clearly indicated in said View.

In order that the I-beam 26, with the upper die element or platen 10,and the several bracket connections and levers may be supportedtemporarily, while filling the mold cavities in the lower die element orplaten.

or for other purposes, and to avoid an undue strain upon the liftingcylinder, the supporting frame 30 for the latter is provided with aseries of depending hooks '38, and the I-beam 26 carries eye members 39,to be engaged by these hooks.

The continuous passages within the respective. die elements or platensfor the circulation of the temperature-controlling medium (usuallysteam), are provided with inlet and discharge openings, indicated at a,and 6, respectively. By preference these passages are arranged ordisposed as independent, sections; the respective platens shown in thedrawings having four such sections, indicated at A, A, A and A 7In'order that the platens may be positioned laterally to insure registryof the respective mold cavities, one platen, the upper one for instance,may have the edges of its meeting face recessed, as indicated at 0,while the other platen will be provided with edge flanges (Z, fittingthese recesses, as clearly shown in Fig. 4.
